Screws and Attachments for Plastic Enclosures
Moulded bosses without threads are provided in most Bopla plastic enclosures. The screws to be used have self-shaping threads and should be slected from the tables below and ordered as an accessory.
In selecting the screws the internal diameters of the bosses and the depth of the hole shown in the drawings should be taken into account.

Distance bolts
These bolts enable mounting plates to be set high or sandwiched on moulded bosses without threaded sleeves.
The outside threads are laid out for moulded bosses with an internal diameter of 2.4 - 2.6 mm. The inside threads are M 3. In selecting the length of thread, the depth of the moulded bosses and any mounting plate already installed need to be taken into account.
